You enter this cave through door D. Door C at the other end provides access to Pale Pass. For stealthy characters, the narrow corridors make sneaking past enemies very challenging. The numerous twists and turns can make the cave somewhat mazelike, although watching your map helps make it clear that there is only one path through the cave.

The one noteworthy item in the cave is the set of Akaviri Orders (E). Although you do not need the orders to complete the quest, having them provides you with an easier option for how to complete the final stage of the quest.

Akaviri Orders at location E on map. The orders are lying next to a skeleton, presumably the corpse of the Akaviri messenger. Your journal will update as soon as you approach the area to make sure that you notice the orders.
